A good area to focus on is using a range of tenses – not just

past / present / future but things like “perfect , continuous

and modal forms”.

就是后面这句难到我了"perfect , continuous and modal forms "
可不可以译成:

不仅仅要使用过去时,现在时,将来时等时态

还要多用些范句

完成时,进行时和情态动词

我式一下解封没有

完成时、进行时和（不知道是语调还是情态动词）

什么是PRESENT PERFECT CONTINUOUS啊？ perfect , continuous and modal forms 怎么翻? Future Simple,Future Perfect,Future Continuous,Present Continuous,be going to联系与区别 Future Simple,Future Perfect,Future Continuous,Present Continuous,be going to联系与区别 `PERFECT continued continuing continuous区别 perfect keylogger? perfect disk constant和continuous的区别 past passive continuous tense是什么意思？
